@boss06 mine is smaller bc i removed 2 polygons from the model.
And i imported and exported it in 3ds max.
I think you would notice the same difference, if you would compare the original unmodified model vs my edited one.

@boss06 i took a look, and the one for the "social network building" mod seems to identical to the one from the billboards mod.
so i don´t need to adapt the one from the billboards mod, bc you can just use the one i already did for that social network building mod
